----------------------------------------
Summary: FileInstall throws Interrupted exception when refreshed
Key: FELIX-3712
URL: https://issues.apache.org/jira/browse/FELIX-3712
Project: Felix
Issue Type: Bug
Components: File Install
Affects Versions: fileinstall-3.2.6, fileinstall-3.2.4
Reporter: Per-Erik Svensson
FileInstall will throw exception when refreshing. It is possible there are
easier ways to reproduce this but here is one way:
1) Uninstall gogo command (if available) from the osgi container.
2) Install fileinstall
3) Put gogo command in the directory watched by fileinstall
Result: Fileinstall throws
In main loop, we have serious trouble: java.lang.RuntimeException:
java.lang.InterruptedException

Possible reason: Due to FELIX-3424, the refresh() method in DirectoryWatcher
was changed from calling
packageAdmin#refreshPackages() directly, to using the FileInstall#refresh()
helper method. The later wraps interrupted excpetions in a runtime exception
which is never caught in the directory watcher's main loop. Thus, the directory
watcher will re-throw the exception, which it previously did not (since the
interrupted excpetion would get caught).
